Puerto Rico and other US territories are not part of any census region or census division.[7]

Standard federal regions

Standard federal regions.

The ten standard federal regions were established by OMB (Office of Management and Budget) Circular A-105, "Standard Federal Regions," in April, 1974, and required for all executive agencies. In recent years, some agencies have tailored their field structures to meet program needs and facilitate interaction with local, state and regional counterparts. However, the OMB must still approve any departures.

Federal Reserve banks

Energy Information Administration

PADD I can also be subdivided into 3 Subdistricts:

PADD system was established in World War II and therefore don't accurately reflect current trends. The EIA has updated the PADD system with a complimentary set of regions to reflect this and will change it to suite current needs. (Note: Region 9 includes countries not part of the USA but is included for the sake of completion since it contains Puerto Rico)
